hi guys my site is doing very well in Google search engine with good keywords but their is nothing about my site using that keywords in Yahoo SE... what is the problem??
You need to optimize your website for yahoo especially doing high on-page optimization and utilize their high keyword density capacity to leverage more potential keywords. Also use yahoo site explorer to track out your site web stats effectively.
Silly question, are you using the Meta Keyword tag? Sites we have that we remove it are doing very bad too.
